REEL FOR HARVE STERS.

$PECIPICATION forming part of Letters Patent No. 375,694, dated December 27, 1887.

Application filed September 2i, i885. Serial No. 177,768. (No model.)

To all whom it 11mg concern.-

Be it known that we, J. CALDER CUNNING- HAM and GEORGE A. CUNNINGHAM, of Washington township, in the county of Jackson, (St.

lllaryspost-oiiice, county of Pottawatomie,)

State of Kansas, have invented anew and useful Improvement in Reels for Harvesters, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of a harvester 15 to which our improved reel has been applied, partly in section, and parts being broken away. Fig. 2 is a plan view of the same, partly in section, and parts being broken away.

The object of this invention. is to provide reels for harvesters constructed in such a manner that they can be readily raised and lowered and will be securely held in every position.

The invention consists in the combination, with the reel and its driving mechanism, of

I an adjusting and holding mechanism, such as will be hereinafter fully described, and then pointed out in the claim.

This invention is restricted to the reel and its operating mechanism, the other features 0 shown in connection therewith being the same as those shown in my Patent No. 838,219, and granted March 16, 1886.

Referring to the drawings by letter, A represents the platform frame, to the front of 5 which is attached a finger bar, B, having guard-fingers O, and provided with a sicklebar having cutters E, working in the said guardfingers O.

F is a wheel for supporting the grain end of 0 the harvester, having its journal attached to the slide G,which works in ways on the frameA. H is a frame, in the rear end ofwhich is journaled the drive-wheel I and in the forward end the caster-wheel J. Supported upon J, 5 the frame H is the seat K, and to the forward part of the machine is hinged the tongue L. The outer j ournal of the drive-wheel I proj ects, and upon it is mounted the chain-wheel M.

N is a lever pivoted to the frame at a, and

by means of which the clutch N is operated.

O is an endless chain passing around the chain-wheel M and the chain-wheel P, mounted in abraeket, b, on the frame A. To the chainwheel P is connected a bevel gear-wheel, Q, the teeth of which mesh into the teeth of a small beveled wheel, R, on the shaft S. On the forward end of the shaft S is mounted the chain-wheel T, around which passes the end less chain U. The endless chain passes around the chain-wheel V, to which is connected the beveled gear-wheel V, the teeth ofwhich mesh with the teeth of the beveled gear-wheel X. With the beveled gear-whecl Xis rigidly connected the chain-wheel Y, around which passes the endless chain Z. The endless chain Z also passes around the chain-wheel c. \Vith the chain-wheel c is rigidly connected a chainwheel, (1, around which passes the endless chain c. The endless chain c also passes around the chain-wheelf on the end of the reel'shaft g,which revolves in the forward end of the lever h. The lever h passes through a slot in the upper end of the reel-post i, and is pivoted on the journal of the chain-wheels a (Z. The rear arm of the lever h passes through a slot in the'curved catclrbar j, the ends of which are attached to the upper and lower parts of the reel-post z, and serves as a brace to strengthen the said lever against lateral movement. In the convex side of the eatch-bar j are formed teeth k, with which engages the pawl Z, pivoted to the lever h. The pawl Z is held down against the teeth 70 by the spring m, attached to said lever.

To the forward part of the pawl Z is pivoted the forward end of the bar a. The bar it rests and slides upon the upper side of the lever h, and is kept in place by a link, 0, pivoted to it and to the said lever, or by other suitable guides or keepers. The outer end of the bar a is enlarged or provided with a handle for convenience in operating it to withdraw the pawl Z from the catch-teeth k, to allow the lever h to be operated to raise and lower the reel as the height of the grain may require. The reel-shaft g is provided with the arms 9 and the bars 9 in the ordinary manner. 1) is an inclined grain-guard plate attached to the rear part of the platform of the frame A.

Having thus fully described our invention, I00

we claim as new and desire to secure by Letters Patent- In a grain-harvester, the combination, with the reel-post 1', provided with the slotted and 5 curved rack-barj 7c, of the lever h, fulcrumed I on the post i, the reel-shaft g, journaied in the i sliding bar n, and means for operating the [O chain-wheel Y from the drive-Wheel, substantially as herein shown and described.
